STRAINER Filed Oct. 9, 1939 INVENTOR fieczmrsak I a BY M (01% 1 I AT RNEYS Patented July 29, 1941 UNITED STTS s'rnsmnn Fred Metsch, Cleveland, Ohio Applicationoctober 9, 1939, Serial No. 298,696 2 Claims. 101. 210-159) This invention relates to a strainer which is particularly adapted for use by painters for straining varnishes, enamels, and other paints which should be thoroughly strained before being used. It is to be understod, however, that use of the strainer is not limited to varnishes and paints as it is of general utility and. may be used for straining any material needing such treatment.'

' One object of the invention is to provide a strainer having a main ring or annular body and a clamping ring by means of which a straining cloth is held in a tightly stretched state across thelower end of the annular body, the body being provided with means for supporting the same in the upper portion of a paint bucket or other container into which the material being strained flows from the strainer.

Another object of the invention is to so form the clamping ring and the lower portion of the annular body that they taper downwardly and have wedging fit causing the strainer cloth to be very firmly gripped and held tightly stretched when the body is forced into the clamping ring.

Another object of the invention is to so form the ring that after the cloth has been applied and the annular body thrust downwardly into the ring, the ring may be grasped by an outstanding flange and drawn upwardly very firmly into place.. 7

Another object of the invention is to provide the annular body with supporting means of such formation that the strainer may be supported in operative relation to containers of different diameters.

Another object of the invention is to provide a strainer which is of simple construction, very strong and durable but of light weight and capable of being manufactured at small cost and sold at a low price.

Still another object of the invention resides in providing a device which is simple and durable in construction, inexpensive to manufacture and one which will be very eflicient in operation and application to use.

With these and numerous other objects in view, my invention consists in the novel features of construction, combination and arrangement of parts as will be hereinafter referred to and more particularly pointed out in the specification and claims.

The invention is illustrated in the accompanying drawing wherein:

Figure 1 is a side elevation showing the annular body and the clamping ring separated.

Figure 2 is a side elevation of the assembled strainer.

' Figure 3 is a top plan view of the strainer.

Figure 4 is a view upon an enlarged scale showing the improved strainer in section along the line 4-4 of Figure '3 and supported upon a receptacle in position for use- V This improved strainer has an annular body I formed of sheet metal or'other suitable material and of such diameter thatitwill fit within a paint bucket or other container 2 in spaced relation to walls thereof. The strainer is preferably spaced from walls; of the container an appreciable extent, as shown in Figure A, but it is to be understood that the strainer may be of any diameter desired and ,used in connectionjwith any container into which it will fit, The upper lower ends thereof, and in order to firmly hold the arms to the body, inner end portions of the strips forming the arms are .bent upwardly to form anchoring portions 5; These anchoring portions are secured against the body by welding or solder with their upper ends abutting the bead 3 so that they will be held in their proper positions when applied and braced against upward movement to prevent them from being broken loose by weight of material in the strainer during use of the strainer. Outer ends of the arms are bent to form depending bills 6 which limit longitudinal shifting movement of the arms across the upper edge of the container and prevent them from slipping out of engagement with the container. Therefore, the strainer cannot shift outrof its proper position relative to the container and drop into'strained material in the container.

The lower end portion 7 of the annular body is tapered downwardly as shown in Figures 1 and 4, r

strainer cloth which extend upwardly betweenthe ring and the tapered lower portion of the body. During assembly of the strainer, the clamping ring is set upon a fiat surface and the strainer cloth set in place upon the ring. The

body I is then disposed above the ring and moved downwardly so that its lower end engages the cloth and carries the same downwardly into the ring. The dimension of the ring relative to the tapered portion of the body is such that a close wedging fit is established and the cloth firmly held in a stretched condition. After the tapered lower portion of the body is engaged in the ring, the ring and body are lifted by engaging the fingers under the outstanding annular flange I of the ring and-the thumbs over the rolled upper edge of the body and upward pull is exerted upon the flange to force the ring upwardly until it is firmly in place and the cloth tightly stretched and secured about the body. The strainer may then be set in place in the upper portion of a paint can or other container where it will be supported by its arms 4 resting upon the can as shown in Figure 4. The paint or other material to be strained is poured into the body and drips through the cloth into the container. A cloth of either coarse or fine weave may be used according to the material to be strained and after the straining has been completed, the cloth can be easily removed by slipping the ring downwardly after removing the strainer from the container. 'The cloth may then be discarded or cleaned and put away for futureuse.

Having thus described the invention, what is claimed is:

1. A strainer comprising an annular body open at its top and its bottom and having its lower portion tapered downwardly and its upper portion rolled outwardly to form an outstanding bead about the upper edge of its annular wall, and a downwardly tapered clamping ring of less depth than the tapered portion of the body and conforming to the taper thereof for fitting snugly about the tapered portion of said body and gripping marginal portions of a strainer cloth to hold 7 the cloth in a stretched condition across the open bottom of the body, the upper portion of said ring being formed with an outstanding annular flange for engagement by the fingers of the operator when drawing the ring upwardly to a clamping position.

2. A strainer comprising an annular body having its lower portion tapered towards its lower end, an outstanding bead about the upper end of the body, a downwardly tapered clamping ring for fitting about the tapered portion of said'bodyand gripping .portions of a strainer cloth to hold the cloth in a stretched condition across the lower end of the body, an outstanding finger-engaging flange about the upper end of said ring, and arms for supporting the strainer extending radially from the body in spaced relation to each other circumferentially thereof and having their inner end portions bent upwardly to form shanks secured against the body with their upper ends abutting said bead to brace the shanks against upward strain, outer ends of the arms being bent to form depending bills for limiting movement of the arms across the upper edge of a container having the strainer supported thereon.
